Exploring Cagliari by sea is one of the most beautiful ways to experience Sardinia. From iconic landmarks like the Devil’s Saddle to hidden coves and crystal-clear snorkeling spots, the coastline of the Gulf of Cagliari looks completely different from the water.
In this guide, you’ll discover the best places to see in Cagliari by boat — plus a few local tips to make your experience unforgettable.
Poetto Beach and the Gulf of Angels
Poetto is Cagliari’s famous long beach, stretching for kilometers along the Gulf of Angels. From the sea, you can enjoy wide open views, turquoise water, and a stunning panorama of the city in the background.
Best for: relaxing swim stops, panoramic views, calm waters.
The Devil’s Saddle (Sella del Diavolo)
The Devil’s Saddle is Cagliari’s most iconic landmark. Its dramatic limestone cliffs rise right above the sea between Poetto and Calamosca, creating one of the most scenic stretches of coastline in the area.
From a boat, you can admire the rock formations up close, spot hidden inlets, and swim in crystal-clear water away from the crowds.
Best for: snorkeling, photos, cliff views, unique scenery.
Cala Fighera (Wild Cove & Cliffs)
Cala Fighera is a wilder, more rugged corner of the coast — surrounded by high cliffs and deep blue water. It’s one of the most exclusive spots to experience by sea, especially when the water is calm.
Best for: authentic nature, quiet swim stops, dramatic cliffs.
Calamosca Bay
Calamosca is a small bay nestled at the foot of the Devil’s Saddle area. By boat, it feels peaceful and intimate, perfect for a refreshing dip and a relaxed break along the route.
Best for: calm swim stop, relaxing atmosphere.
Hidden Caves and Secret Corners
One of the best things about exploring Cagliari by sea is discovering small caves, natural pools, and hidden corners that are hard (or impossible) to reach from land.
Depending on sea conditions, a boat tour may stop in secluded areas perfect for swimming and snorkeling.
Best for: discovering hidden places, clear water, privacy.
Gasole Natural Pools (Le Piscine di Gasole)
Among the hidden gems of the Gulf of Cagliari, the natural pools of Gasole are one of the most exclusive and lesser-known spots to discover by boat. These shallow, crystal-clear waters create a natural swimming area surrounded by rocky formations and unspoiled coastline.
Accessible only by sea and depending on weather conditions, this area offers a peaceful and authentic experience far from crowded beaches.
Best for: crystal-clear water, snorkeling, quiet and exclusive swim stops.
